Title: Electric discharge lamp
IPC: H01J17/06
Filed: 1969-07-10
Abstract: 1,222,089. Glow discharge lamps. SYLVAMA ELECTRIC PRODUCTS Inc. 10 July, 1969 [10 July, 1968], No. 34880/69. Heading HID. A gas discharge flicker lamp has two electrodes bearing a coating comprising a mixture of a metal halide and a partially decomposed alkaline earth azide. The addition of the halide to the usual azide coating enables the lamp to operate with quantities of nitrogen up to 0.1% in the filling. The coating mixture may comprise barium azide and cesium azide together with from 0.5 to 50% by wt. of a halide of barium, strontium, calcium or cesium, e.g. 2% of barium iodide. This is applied in the form of an aqueous solution to the electrodes which are made from thin perforated iron sheet. The lamp envelope is repeatedly heated with gas flames and repeatedly flushed, first with nitrogen, then with neon. The coating partly decomposes with evolution of nitrogen. The filling may comprise neon at a pressure of 110 mm. The external surface of the lamp may be covered with glass beads.

Title: Methods of Treating Textile Linear Material
Inventor: JONES EVAN ISLWYN
IPC: D02G1/00
Filed: 1967-07-31
Abstract: 1,198,114. Crimping yarns. G. H. HEATH & CO. Ltd. 30 July, 1968 [31 July, 1967], No. 34979/67. Heading D1F. A method of treating or modifying, e.g. crimping or bulking, textile linear material, e.g. single or composite, polyethylene terephthalate or nylon yarn and bands of film material "of the kind which yield to fibrillation or filamentation", e.g. polypropylene ribbon, comprises forming the material into at least one loop and intertwining the leading and trailing ends in the loop a multiplicity of (possibly preformed) turns so that the intertwining zone and the loop zone form one major loop circuit to enable the leading and trailing portions of the travelling material to assist passage of each other through the intertwining zone. Differential tensions may be applied to the leading and trailing portions of the material, e.g. so that the latter portion remains relatively straight and forms a core around which the other portion spirals. The material may be coiled upon itself first in one direction and then in the other: it may be heated (to set the deformation therein) in the intertwining zone and then naturally or forcibly cooled. The treatment may be combined, and/or form part of a sequence of successive treatments, with extrusion, drawing, texturing, stuffer-box crimping, down-twisting, plying, knitting, lubricating and/or cutting. In the apparatus shown in Fig. 2, yarn at 4 passes through tension discs 5 and guides 6 and 9, over positively driven rollers 10, 11, to return through guides 6, 9, between which it coils several turns 8 around itself having formed a complete loop 7 so that both portions of the yarn in the intertwined coils travel in the same direction: from guide 9 the yarn passes between positively driven nip roller 14 and on to a windup package 16. Electric plate or block heater 12 or 13 is operated at controlled temperature by thermostatic servomechanism (not shown) to plasticise the yarn. A multiple loop arrangement, Fig. 4 (not shown) extends the healing length of the looped yarn within a heat box (28) while maintaining the trailing yarn portion at a lower temperature. Resultant twist-lively yarns of opposite torque may be plied. The required coil turns may be preformed in the yarn by use of a false-twist spindle, rotated only during such initial coil formation, Figs. 5a-d (not shown) the number of coils per inch being between that suitable for the false-twisting of the denier of the material in use and the twist suitable for a material of twice this denier.

Abstract: 1,111,852. Textile treating apparatus. PAVENA A.G. 16 Aug., 1965 [24 Aug., 1964] No, 35035/65. Heading D1L. A method of continuously treating a staple fibre sliver with liquid comprises the steps of forming the sliver into a tubular shape and passing it continuously through a guide zone A in which it is externally and internally supported, introducing liquid under pressure into the middle of the tubular shape which has passed into a free zone B, excess liquid escaping radially, compacting the sliver by passage through a funnel shaped guide member 6 and subjecting the compacted sliver to circumferential compression in a zone D. The conduit 5 supplying the liquid extends through the guide zone A and forms the internal support for the sliver. The circumferential compression is effected by means of a pair of discs 8, 9 forming a press-nip. The free zone B is of a length less than the maximum staple length of the sliver fibre material and preferably less than the mean staple length thereof.

To facilitate engagement of a positive clutch between members b, c having internal teeth d, f respectively, wherein a ring a having external teeth e in driving engagement with the member b is axially moved by hydraulic means to drivingly engage also the member c, the ring a is resiliently connected to the member b for circumferential movement limited by engagement of the teeth d, e which are of the same circumferential size and form but double the circular pitch, and hence half the number, of the teeth f so that should the teeth e, f, the leading ends of which are streamlined as shown, be out of register, the ring a will be circumferentially deflected until register is effected. The resilient connection between the ring a and the member b comprises three or more equally spaced flexible rods g each rigidly fixed at one end to the ring a and spherically jointed at the other end to a cylinder h which is free to slide in a lapped bore k in the member b. In the unstressed condition of the rods g the teeth e lie midway between the teeth d. The ring a is moved by hydraulic pressure admitted through lines l, m to a chamber n for clutch engagement and through lines o, p to a chamber q for disengagement.
